A Social Entrepreneurship Perspective of De‐Carbonising the Footprint through Recycling Compensation: A Case Study of the NGO Madre Coraje

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This research analyses the carbon footprint of the NGO Madre Coraje, using an integrated methodology that combines the calculator provided by REAS (Red de Economía Alternativa y Solidaria) Navarra and the Life Cycle Assessment (LCA). It quantifies emissions across the three scopes of the Greenhouse Gas Protocol, evaluating both direct and ...

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability

Deep Underground Science and Engineering, EarlyView.
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

Deep Underground Science and Engineering, EarlyView.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring
